- Abstract
The relaxation properties of the Rouse chain with inhomogeneous links have been investigated. The problem has been solved by direct integration of systems of differential‐difference equations which describe the relaxations of the chain length and stress. It has been shown that these two processes are different in both the set of relaxation modes and the characteristic of the spectrum. The influence of the chain structure on these parameters has been demonstrated. The effect of “packing” of the relaxation modes has been revealed; it appears on introduction of links with an increased coefficient of friction into the chain and manifests itself in the fact that the high‐frequency modes come closer together and even merge, so that their total number becomes substantially smaller than that in the case of the Rouse model.
